Hi,

> On a separate topic, how does the web browser discover the CHIRIMEN device?  

CHIRIMEN is also Web browser, we assume mechanism of the information exchange between the Web application for the time being. We recognize that Discovery-related discussions and specifications about Web Browsers has been performed in various places. And by checking in at the web server as a hub, there is also much general  application services which exchanges information among browsers such as qwebirc Web-IRC gateway, facebooke messenger and slack etc.

Accroding to *1.
*1: http://www.w3.org/Mobile/mobile-web-app-state/ 

>>The Network Service Discovery API*2 offers to discover services on the local network (such as the ones offered via DLNA), enabling mobile Web applications to integrate seamlessly with these services.
>>An alternative proposal to the Network Service Discovery API has emerged: Named Web Sockets*3 offers to provide well-known sockets to existing and approved local network services.

Second Screen Presentation Working Group*4 also mentions Network Service Discovery

And other discovery related information at W3C.*5-*8

We CHIRIMEN Open Hardware Project is pursuing the integrated world which ordinary web browsers having applications execution environment by Javascript behaves also as servants or one of web platform for WoT. More nearly rather than the Javascript processor which does not contain a web browser. It will be because various investigations and specifications for web Apps on web browsers may be useful, and it is easy to use the web browser itself to enjoy its benefit thoroughly.

Satoru

It could be interesting to look at a web platform for JavaScript based apps that combines the app facing APIs we’ve been discussing in this IG along with the work being done in the Web Apps WG on manifest and service workers.  Is this also something of interest to you?

Given that we’re positioning the W3C as defining inter-platform standards, it would make sense for us to try to relate these different architectures.  Where should this work be written up?   For instance, the technology landscape document, the Web of Things architecture document, or perhaps something new?
